If an owner wants the charging to stop at 80%, that is about 3.5 - 4.0 kWh less than a full charge in a 3 year old car.
L1 at 1.2 kW ? Set the end timer 3 hours later than needed
L2 at 4 kW ? Set the timer 1 hour later than needed.
So basically this is just more or less guess work on the S? After driving today, I am currently at 61% charge and if I wanted it at 80% I would L1 charge for about what? Five hours? So if I plugged in at 7pm, I would set the timer to end at 3am rather than midnight?
SageBrush is saying the car is smart enough to know when to start charging if you set the timer.
The car will start charging only early enough to get it to 100% by the timer time your set.
Let's say the car charges 5% every hour. Let's say you have 60% battery left.
To charge the remaining 40% to make it 100% full, the car will need 40/5 = 8 hours to fully charge it.
If the current time is 8 pm and if it starts charging now, at 4 am, it will be 100% full.
If you set the timer to 8 am, the car will start charging at midnight because it needs 8 hours of charging time.
Now, If you set the timer to 11 am, the car will start charging at 3 am.
If you unplug it at 8 am, the last 3 hours of charging will be not done and you will be 3x5% = 15% below 100%, which is 85%.
So SageBrush is saying set it to about 3 hours later than the time you will unplug it to go to work so it will be that much short of 100%.
